Williams Equipment Corporation and its insurer (hereinafter referred to as “employer”) contend the Workers’ Compensation Commission erred in (1) finding that Donald L. Register (claimant) proved that the surgeries, tests, and physical therapy prescribed by Dr. John Biddulph were medically reasonable and necessary; and (2) awarding claimant attorneys’ fees as a result of its finding that employer’s defense as to pre-authorization did not have a reasonable basis. Upon reviewing the record and the parties’ briefs, we conclude that this appeal is without merit. Accordingly, we summarily affirm the commission’s decision. Rule 5A:27.

In ruling that claimant proved that his treatment, tests, surgeries, and physical therapy were reasonable, necessary, and causally related to his compensable March 13, 2000 injury by accident, the commission found as follow:

Dr. Biddulph’s reports establish that the treatment provided by him and his designees was both reasonable and necessary and causally related to the compensable injury. As noted by the Deputy Commissioner, the June 8, 2000 surgery; the October 17, 2000, follow-up surgery; the December 12, 2000, left shoulder surgery; the follow-up physical therapy sessions; the anesthesia; and the August 2000 MRI were all necessary, reasonable, and causally related. The medical evidence presented which questions the reasonableness, necessity, and causal relationship of the treatment to the compensable injury is the opinion of Dr. [Anthony] Debs. We attribute greater weight to the treating physician’s opinion.

Dr. Biddulph’s reports and opinions provide credible evidence to support the commission’s findings. As fact finder, the commission was entitled to accept the opinions of the treating physician, Dr. Biddulph, and reject the contrary

Code ??65.2-713 provides that if the commission finds that an employer or insurer has brought or defended a proceeding without reasonable grounds, it may assess costs, including a reasonable attorney’s fee. Whether to award attorney’s fees and costs against an employer who has defended a proceeding without reasonable grounds is within the sound discretion of the commission. See Jensen Press v. Ale, 1 Va. App. 153, 159, 336 S.E.2d 522, 525 (1985).

Employer denied payment of the medical bills at issue, contending that the surgeries and treatment were not pre-authorized. Employer took this position in its position statement filed with the deputy commissioner. Clearly, the Workers’ Compensation Act did not require claimant to obtain pre-authorization from employer to undergo treatment by Dr. Biddulph. Accordingly, the commission did not abuse its discretion in awarding claimant attorney’s fees pursuant to Code

??65.2-713, due to employer’s denial of payment based on the defense that the procedures had not been pre-authorized.[2]

For these reasons, we affirm the commission’s decision.

Affirmed.

[2] We note that the commission awarded claimant a portion of the attorney’s fees, $1,000, but declined to award him the remaining $1,000, based upon its finding that employer’s defense as to responsibility for the surgeries had a reasonable basis, but the defense as to pre-authorization did not.
